Calculate New Extrusion Multiplier

The Extrusion Multiplier Calculator is a handy tool for 3D printing enthusiasts who want to optimize their printing settings. By accurately calculating the new extrusion multiplier, users can achieve better print quality and consistency.

Formula: The new extrusion multiplier (EM) is calculated using the following formula: New EM = (Measured Width / Expected Width) * Current EM

How to use:

1. Enter the expected width in millimeters (mm).
2. Input the measured width in mm.
3. Provide the current extrusion multiplier.
4. Click on the “Calculate” button to get the new extrusion multiplier.

Example: Let’s say the expected width is 20 mm, the measured width is 19.5 mm, and the current extrusion multiplier is 1.2. After entering these values and clicking “Calculate,” the new extrusion multiplier would be approximately 1.17.

FAQs:

1. What is an extrusion multiplier?
   • The extrusion multiplier (EM) is a setting in 3D printing slicer software that adjusts the amount of filament extruded during printing to achieve the desired print quality.
2. Why is the extrusion multiplier important?
   • The extrusion multiplier ensures that the correct amount of filament is extruded, affecting the overall print quality, strength, and dimensional accuracy of the printed object.
3. How does the expected width differ from the measured width?
   • The expected width is the intended width of the printed object, while the measured width is the actual width measured after printing.
4. What does a higher extrusion multiplier indicate?
   • A higher extrusion multiplier means more filament is being extruded, which can result in thicker lines and potentially over-extrusion if not calibrated properly.
5. Can the extrusion multiplier vary between different filaments?
   • Yes, the extrusion multiplier may need adjustment when using different filaments due to variations in filament diameter and material properties.
6. How often should I recalibrate the extrusion multiplier?
   • It’s recommended to recalibrate the extrusion multiplier whenever changing filament types, adjusting print settings, or encountering print quality issues.
7. Does the extrusion multiplier affect print speed?
   • While the extrusion multiplier itself doesn’t directly affect print speed, adjusting it can impact print quality, which may indirectly affect print speed.
8. What if I don’t know the expected width?
   • If you don’t have a specific expected width, you can use the measured width as a reference for calibration and adjustment of the extrusion multiplier.
9. Can the extrusion multiplier be less than 1?
   • Yes, the extrusion multiplier can be less than 1, indicating under-extrusion, which may be necessary for fine-tuning print settings and improving print quality.
10. Are there other factors besides the extrusion multiplier that affect print quality?
    • Yes, various factors such as layer height, print temperature, print speed, and bed adhesion also influence print quality and should be considered during calibration.

Conclusion: The Extrusion Multiplier Calculator is a valuable tool for 3D printing enthusiasts to fine-tune their print settings and achieve optimal results. By accurately calculating the new extrusion multiplier, users can enhance print quality, reduce waste, and save time during the printing process. Experimenting with different extrusion multipliers can lead to better understanding and mastery of 3D printing techniques.
